[Dri-devel] R200: Why is SW TCL faster?

Hello,


I have a Radeon 9000 64 MB DDR AGP card and I've been running it on a
2Ghz Intel Pentium IV machine running the latest madrake
distribution.


I've installed the latest CVS on my machine (well as of yesterday) and I've
notice something strange.  When disabling HW TCL (R200_NO_TCL) I seem
to get faster frame rates.  This is most noticeable when running the
atlantis demo (800x600) especially if you increase the number of
sharks (50-200) though it's still noticeable with only one shark. This
seems very counter-intuitive to me. Does anybody else see this?  Any
idea what could be happening?


Thanx,

jOrGe W.
